최근 들어 기후변화로 인한 극심한 가뭄 피해가 한반도에 발생하고 있다. 가뭄 상황에 대비하여 댐을 안정적으로 운영하기 위해서는 갈수빈도 유입량에 대한 분석이 필수적이다. 갈수빈도해석의 경우, 홍수빈도해석과 유사하게 확률밀도함수의 극값에 대한 확률값을 산정하며, 확률 분포형의 역함수에 비초과확률을 대입하여 산정한다. 그러나 홍수와 달리 가뭄은 지속기간이 긴 특성 탓에 자기상관을 고려해야하며, 댐 및 저수지 등 대규모 시설물의 경우 일반적인 하천과 달리 저류효과로 인해 누적 유량에 대한 고려가 필요하다. 이에 K-water는 자체 제작한 누가차분법 및 Disaggregation 두 가지 방법을 채택하여 실무에서 사용해왔다. 그러나 누가차분법을 사용할 경우, 빈도유입량이 지나치게 크게 산정되는 문제가 있으며, Disaggregation 방법을 사용하는 경우, 특정 빈도 이상의 극한가뭄에서 유입량의 차이가 유의미하지 않아 산정된 빈도유입량과 최근 발생한 극심한 가뭄의 실측유입량간 큰 차이가 발생하고 있다. 따라서 본 연구에서는 자기상관을 고려한 선형회귀모형에 근거하여 빈도유입량을 배분하는 방법을 제안한다. 또한, 앞서 서술한 네 가지 빈도유입량 방법(월빈도분석, 누가차분법, K-water Disaggregation, 자기상관 선형회귀모형)에 대한 수식적 비교를 수행하며, 국내 댐 유역에 적용 및 평가를 통해 자료 특성에 따른 적절한 빈도유입량 산정방식에 대한 기준을 제안한다. 본 연구를 통해 가뭄특성을 고려한 합리적인 댐 유입량을 산정함으로써 보다 유연한 수자원시설물의 가뭄대응이 이루어질 것으로 기대된다.

In order to visualize point based Location-Based Social Network Services(LBSNS) data on multi-scaled tile map effectively, it is necessary to apply tile-based clustering method. Then determinating reasonable numbers and size of tiles is required. However, there is no such criteria and the numbers and size of tiles are modified based on data type and the purpose of analysis. In other words, researchers' subjectivity is always involved in this type of study. This is when Modifiable Areal Unit Problem(MAUP) occurs, that affects the results of analysis. Among LBSNS, geotagged Twitter data were chosen to find the influence of MAUP in scale effects perspective. For this purpose, the degree of spatial autocorrelation using spatial error model was altered, and change of distributions was analyzed using Morna's I. As a result, positive spatial autocorrelation showed in the original data and the spatial autocorrelation was decreased as the value of spatial autoregressive coefficient was increasing. Therefore, the intensity of the spatial autocorrelation of Twitter data was adjusted to five levels, and for each level, nine different size of grid was created. For each level and different grid sizes, Moran's I was calculated. It was found that the spatial autocorrelation was increased when the aggregation level was being increased and decreased in a certainpoint. Another tendency was found that the scale effect of MAUP was decreased when the spatial autocorrelation was high.

The purpose of this study was to investigate the effects of career maturity major satisfaction, self-control on university students' job stress. Data collection was conducted from November 2018 to February, 2019 in 236 students who understood the purpose of the study and agreed to participate in the study. The collected data were analyzed by frequency, mean, standard deviation, Pearson correlation analysis, and multiple regression. The lower the career maturity (β=-.258), job stress was the higher. Also, the lower major satisfaction (β=-.377), the higher the job stress, and the lower the self-control (β=-.275), the job stress was the higher. Through these results, education programs that link students from their childhood to college students are needed to improve their career maturity, satisfaction with majors and self-control(r=-.410, p<.001).

The purpose of this study is to examine the mediating effects of self-acceptance and counselor activity self-efficacy on the relationship between counselor's perfectionism and psychological burnout. For this purpose, 325 data samples were collected from the counselors who are currently working. The results of this study are as follows. Self-oriented perfectionism had a significant positive correlation with other-oriented perfectionism, socially-prescribed perfectionism, and psychological burnout, while it is negatively correlated with counselor activity self-efficacy. Other-oriented perfectionism showed a significant positive correlation with socially-prescribed perfectionism and a negative correlation with self-acceptance and counselor activity self-efficacy. Socially-prescribed perfectionism was in a significant negative correlation with self-acceptance and counselor activity self-efficacy. Self-acceptance showed a significant positive correlation with counselor activity self-efficacy and a negative correlation with psychological burnout. The counselor activity self-efficacy was negatively correlated with psychological burnout. self-acceptance and counselor activity self-efficacy were identified as double mediation variables between counselor's perfectionism and psychological burnout. The results of this study can be used in the education scene to enhance the understanding of the psychological burnout of the counselor and deal with it. Based on these results, the implications and limitations of this study were discussed and suggestions for further research were made.

The purpose of this study is to examine the relationship between self-compassion and binge eating and to examine the mediating effects of negative affect and negative urgency. To validify this hypothesis, 441 college and graduate students were measured self-compassion, negative affect, negative urgency, and binge eating. For the collected data, SPSS(23.0) and AMOS(23.0) were used for descriptive statistics, correlation analysis, and analyzing the structural equation model. The results of this study are summarized as follows. First, the correlation analysis showed significant correlations among self-compassion, negative affect, negative urgency, and binge eating. Second, in the relationship between self-compassion and binge eating, negative affect and negative urgency showed serial mediating effects. This means that for college and graduate students, the promotion of self-compassion can reduce binge eating behavior by sequentially reducing negative emotions and negative urgency. Finally based on these results, practical applications of self-compassion in the treatment of binge eating behavior were proposed.
